CHARLES SCI-IATTE, or NEW YORK, 1ST. Y.

BRUSH.

Applicationfiled March 25, 1919.

To all whom it may concern Be it known that I, CHARLES SGHATTE, a citizen of the United States, and a resident of New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

The present invention relates to brushes, and more particularly to shaving brushes.

The main object of the invention is to provide a brush, wherein the knot is mounted in such a manner upon the stock thereof that it can be conveniently replaced, thereby permitting in barber shops each customer to be lathered with a previously unused knot.

Another object of the invention is to provide a brush stock of the character specified, which can be manufactured on a commercial scale or, in other words, one which is not so difficult to make as to be beyond the reasonable cost of such a contrivance.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation, partly in section, of a brush constructed in accordance with the present invention; and Fig. 2 is a perspective view of the knot gripping means.

In the drawings, the numeral 10 indicates the handle or stock of a brush, provided in one of its ends with a socket 11. In this socket is loosely mounted a thimble 12, that projects a substantial distance beyond the handle and is provided in its head 13, which is disposed within the socket, with a central hole 1 1. This hole is in alinement with a nut 15, that is fixed against movement within the handle. Within the thimble is slidably disposed a clamping body 16, comprising a disk 17 mounted upon a screw thread- Specification of Letters Patent.

ed stem 18, the latter projecting through the hole 14 and its threads meshing with those of-the nut 15. From the disk 17 extend outward, in substantially parallel relation to the longitudinal axis of the thimble 12, a plurality of spring blades 19, the outer ends of which diverge, as clearly shown at 20, and are then bent inward toward the longitudinal axis of the thimble, as clearly appear-sat 21, to form gripping jaws. The diverging ends of the spring blades are adapted to contact with the outer edge of the thimble.

The knot 22 of the brush is made of relatively inexpensive fibrous material, for instance hemp fibers, of which a knot is formed by winding around a tuft of the same a cord 23 or similar means. The tied end of the knot is of a diameter that it can be conveniently placed between the gripping jaws, when the latter are disengaged from the thimble.

'The operation of this device is as follows:In order to release the knot 22 from the handle 10, the operator takes hold with one of his hands of the thimble 12, and grasps with his other hand the handle 10, rotating the latter in a direction so as to partly unscrew the nut 15 from the stem 18. In this manner, the gripping jaws are disengaged from the thimble 12, whereby they recede from and consequently release the knot 22. A new knot may then be inserted, and the handle 10 turned in the opposite direction, whereby the thimble 12 forces, by acting upon the diverging portions 20 of the spring blades, the inwardly projecting portions 21 of the latter into engagement with the knot, firmly holding the same on the handle.

It is obvious that, while herein the invention has been described in connection with shaving brushes, it may be made use of with brushes generally, in which it becomes necessary to replace, from time totime, the knot.

Attention is also called to the fact that,

' while herein a specific means has been described for holding the knot upon the handle, others may be used without departing from the invention, which lies mainly in the provision of a knot gripping means in combination with a mechanism upon the handle. which forces the gripping means into engagement with the knot by a relative movement between the handle and the gripping means.

WVhat I claim is A brush, comprising a handle provided with a socket, a stationary thiInbl'e in said socket projecting beyond said handle, a knot projecting into said thimble, gripping jaws in the form of blade springs in said thimble having diverging outer ends contacting with said thimble and inwardly bent portions adapted to engage with said knot, a stationary nut in said handle, a member connecting said gripping jaws provided with'a screwthreaded stem meshing with said nut, whereby a relative movement between said gripping jaws and said handle causes said thimble to move said jaws into gripping position.

' Signed at New York, in the county of New York, and State of New York, this 12th day of March, A. D. 1919.-
